The UP is really interesting from a technical point of view. Is a small set of sensors (mostly accelerometers) with a battery (up to 10 days of use).

Feelings are good: is lightweight enough to don’t notice when you wear it. You can track steps, sleep and a large set of activities (giving a different meaning to steps informations). There is not web interface yet. The only way to sync your device and view you data is your smartphone.

I started using the new 3.0 version of the app so i don’t know how the previous versions were.

After a week I’m quite happy with this device. Steps are probably overvalued and sleep tracking is not perfect but data seems near enough to reality to be useful. Since I started to test it I tried to sleep more and do more steps and challenge with my friends was really fun. I really miss the web interface. Would be the best addition to this ecosystem.

Anyway I’m probably going to buy an UP24 on january. If you are part of this network add me as friend 😉
